CARBONATING APPARATUS.

sPncIrIcATIoN 'forming part of Letters Patent No. 657,882, dated september 11, 1900.

Application filed April 15, 1899. Serial No. 713,099. (No model.)

T0 L7/Z whom. it may concern:

Be it known that l, EDWARD E. MURPHY, of Somerville, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Oarbonating Apparatus, of which the following is a specification.

This invention relates to apparatus for carbonating water or other liquids.

The object of this invention is tp provide a simple and efficient automatic apparatus which shall produce a thorough mechanical combination of the liquid and the carbonicacid or other gas and in which the carbonating operation is controlled directly by the accumulation of the carbonated liquid, automatically ceasing when a predetermined quantity has been accumulated and automatically starting when the accumulation is reduced.

My invention consists of certain novel features hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, which illustrate a construction embodying my invention, Figure l is a side elevation. Fig. 2 is a vertical sectional view of an apparatus embodying my invention. Fig. 3 is a detail sectional View showing the outlet for the carbonated liquid and the valve controlling said outlet.

Like letters of reference refer to like parts throughout the several views.

A represents a reservoir or receptacle for the carbonated liquid produced by the apparatus to be described. A suitable outlet distributing-pipe B extends down into said reservoir and is connected at its upper end to the outlet-passage B in the coupling O, which is screwed into the top of the reservoir A, with a suitable bushing O between the top of the reservoir and the annular ange C2 on said coupling. This passage B communicates with the passage B2 of the chamber B3, which is screwed into the coupling C at O3. The passage B2 communicates with the outlet B3 of said chamber, and communication between said passage B2 and the outlet B3 is controlled by the valve B4, having a suitable handle B5. Intothe top of the coupling O is screwed the valve-casing E', having a passage D, controlled by the Valve E, having a suitable operating-handle E2. This passage coinmunicates with the passage DAin the coupling O, and through said passage the liquid and gas mixed in the mixing-chamber pass to the storage-reservoir A. In the upper end of the valve-casing E is screwed the lower end of the liquid and gas mixing tube F, and within said ltube is a metallic sponge G, composed of layers of wire-cloth, by means of which the liquid and gas are min utely subdivided in order to facilitate ltheir mechanical combination. This sponge at its lower end rests on the annular flange F' and is held in a compact body by the annular flange I-I of the spray-head H, which is screwed onto the upper end of the mixing-tube F. ln the upper part of said spray-head is located the detachable spray-nozzle l, having a series of diverting-perforations J, and said nozzle is supported in said head by resting on the annular shoulder K of said head, and supported in said nozzle is a strainer L. On the upper ends of said spray head and nozzle is an annular packing M of any suitable material and against which rests the head N, held on the spray-head H by the union N. ln the head N is the inlet water-passage N2, controlled by the check-valve N8. Located on one side of the spray-head is the nose O, communicating with the interior of said head and having an inlet-passage O for the gas-supply and controlled by the valve O2, having a flexible face to adapt itself readily to its seat, and acting against said valve is a coiled spring O3, adapted to assist in operating the valve O2 to close the passage O as the apparatus fills with water. The cap O4 is screwed into the top of the nose O and has an opening in which the upper end of the stem of the valve O2 moves, and against said cap also rests the upper end of said spring O3. The valve E is for the purpose of shutting off between the mixing-chamber F and the reservoir A at any time when desired without interfering with the distribution of the carbonated liquid.

In operation the liquid-supply pipe is connected to a high-pressure pipe under from one hundred and seventy-five to-two hundred pounds pressure, and the gas-supply is connected to a gas-supply tank of, say, one hundred and twenty-five to one hundred and fifty IOO pounds pressure. To prepare the apparatus for actual use, gas is first suppliedA through the passage O and drives out all the air from the apparatus through the pipeB and the outlet B3, after which the Valve B4 is shut off to close the outlet and the ,gas is allowed to reach the pressure required. Water or other liquid is then admitted through the waterinlet N2 under the pressure above stated,

which is above the gas-pressure, and the liquid being cut up by the sponge at once causes the absorption of the gas in the tube on the passage of the liquid to the reservoir Auntil the i apparatus is entirely filled with carbonated liquid up to the perforations J in the nozzie I, when all lthe admitted gas is absorbed and at which time the entire apparatus is under the initial water-pressure and the valve 02,' controlling the gas-supply, is closed 'bythe gradually-increasing gas and water pressure due to the operation of illing `the apparatus with carbonated water. bonated liquid is drawn off through the pipe B, the spray-nozzle I being so constructed as' to'retard the admission ofA water, the carbonated liquid is drawn od faster than the same y amount of water can be lsupplied in the saine period of time through said nozzle, thereby providing room for the entrance of more new gas which enters by the opening of the valve O2, which val-ve is 'opened lon Aaccount of the gas-pressure behind it, which is then greater than the pressure within the tube F, which pressure at that instant has been reduced .by the drawing olf `of the carbonated liquid.l

rising water and consequent pressure in the tube F as said tube fills. The mixing-tube F is of much less diameter than the reservoir A, so that by partially or entirely emptying said tube the reduction of pressure, owing to the reduction of'volume, will cause the admission of new gas by reason of the gas-pressure being su fliciently grea-t to open the valvey O2 and pass into the tube F. As the water continues to iiow in through the nozzle it passes down into ythe tube F and mixes with Y the gas previously admittedto said tube, and as' the volume of water increases the pressure increases and closes the gas-valve O2. As the tube F gradually fills the increase in volufme increases the pressure, and thereby closesthe valve O2 as soon as the pressure exceeds :the

gas-pressure. The admission of .the gas to the tube F is not due to the flo-.w of water into the mixing-chamber, but itsiad-mission is controlled 4by the withdrawal yot' a certain volume of carbonated liquid which causes a reduction fof pressure inthe mixing-tube bel Now when the car-v.

low the initial gas-pressure, so that the gas' under its own pressure passes into the mixing-tube at that instant where it mixes with the water passing down through said sponge contained in the mixing-tube.

,The check-valve N3 is for the purpose of preventing loss of gas in the event of a break in the liquid-supply pipe.

The valve P, having a suitable handle P', controls the air-inlet P2, through which air is allowed to escape from time to time by operating the valve P.

I do 4not limit myself to the arrangement and construction shown, as the same may be Variedwithout departing from the spirit of m-y invention.

Having thus ascertained the nature of rmy invention :and set forth a construction embodying the saine, what I claim as new, and desire to :secure by Letters yPatent of the United States, `isp-- 1. In a carbon-atingapparatus, a liquid-inlet pipe for supplying liquid under pressure,
